## Discrepancy

DURING LOCAL FLIGHT, PILOT NOTICED HYDRAULIC PUMP CYCLING CONSTANTLY.  PILOT ELECTED TO LAND AND CHECK.  LANDING GEAR WOULD NOT FULLY EXTEND.  PILOT COULD NOT GET LANDING GEAR FULLY UP OR DOWN.  EMERGENCY LANDING MADE WITH PARTIAL GEAR ON GRASS STRIP WITH MINIMAL DAMAGE.  FOUND T/E FLAP ACTUATOR SHAFT SEALS (3 ORINGS) LEAKING FLUID CAUSING LACK OF SUFFICIENT PRESSURE TO OPERATE GEAR AND FLAPS.
